[Mailman-Users] 'Taboo-content' filters in Mailman?

[Stephen Ervin]

Hi;
We are contemplating switching about a dozen school list from majordomo
to mailman.
A feature we find very useful in our chaotic environment is 'Taboo-content'
filters, so for example we can prevent .VBS attachments from
proliferating 
through the lists (or attachments in general, for efficiency sake)

I can't see any mention of such capability in mailman documentation...
Have I missed somthing?
Is there? How do others manage this?

Any tips much appreciated!
TIA
